摘要： Improved drilling systems and methods may include piezoelectric actuator(s) in a drill string at one or more locations to minimize or eliminate stick-slip while drilling. For example, piezoelectric actuators may be incorporated into the rock bit or drill bit in the openings in the bit body for receiving the cutters. As another example, the piezoelectric actuators may be incorporated into an independent module that is place on or in the drill string. The independent module may be placed between the top drive and the drill bit or at the top of the drill string near a top drive.

摘要： A scour monitoring system may provide a housing that is separated into multiple segments that are fluidically isolated from each other. The scour monitoring system may be position adjacent to a structure to be monitored for bridge scouring. Each of the segments may provide a water-swellable material positioned near or in contact with a fiber Bragg grating (FBG) cable. If water penetrates a segment, the water-swellable material may expand to deform the FBG cable. The wavelength of the FBG cable may be monitored periodically for changes, thereby providing moisture detection when a change in wavelength is detected.

摘要： A portable inspecting device includes PZT transducers and performs active sensing to measure the characteristics of bolted connections. The PZT transducers are mounted on opposing ends of spring-loaded rods and can be moved apart to accommodate a structure for testing. The springs cause the PZT transducers to push against opposing parts of the structure in a stable but temporary fashion. The device can be physically moved to inspect the status and health of multiple different bolted connections.

摘要： A system and method for heating concrete structures to either prevent the build-up of freezing precipitation or eliminate freezing precipitation on a top surface of the concrete structures. The system includes a heating assembly integrally formed with a concrete structure to apply thermal energy to the top surface of the concrete structure. Optionally, the heating assembly includes heating elements formed of carbon fiber tape. Following formation of the concrete structure, the heating assembly is configured for unified movement with the concrete structure. The system optionally includes a control assembly operatively coupled to the heating assembly. The control assembly selectively powers the heating assembly and can be configured for remote operation. In use, the control assembly can be selectively activated from a remote location to power the heating assembly and heat the concrete structure.
